Moin together, after we already installed the charging pressure indicators of AutoGauge yesterday at the meeting at the Möhnesee, it goes on with me with Öltemp and Lambdaanzeige. But since, as already mentioned by FlorianMark yesterday, the problems start. The supplied dealer has once so estimated a 3/8″ thread, which it is screwed into the supplied adapters. They also have customs dimensions with approx. 7/8″ (resistance approx. 2mm) and another with approx. 16 mm ( 1.5mm incline) External thread. And now the big question: so that I can get suitable thread adapters, I need to know what the 1.8T for thread on oil drain screw or even better on the oil pressure switch has. Does anyone know that? But it gets even wilder now with the Lambda display. There is now already the alternative (according to the installation instructions) between Lambda probes with 2, 3 or (with heated probes) 4 cables. Where do I have to clamp that? The Lambda instrument has three cables. Does it make me crazy, because it only says several times what you don’t want to do, if you don’t want to scrape the probe, but how to do it correctly, it doesn’t say. Just “turn to the manufacturer of the vehicle”. Yes, I should call AUDI now and ask how to install a Lambda display??? HIIIILLLLFFFFEEEE
